Rhode Island officials say they have scheduled anti-mosquito spraying for Sunday in four areas of the state where eastern equine encephalitis has been detected.
Environmental and health officials say the spraying will be done in the evening and overnight hours, weather permitting.
The state has identified the four areas as "critical risk" locations for the disease. The areas include Central Falls, parts of Westerly, West Warwick and northern Rhode Island near the Massachusetts towns of Uxbridge, Douglas and Mendon.
Spraying won't be performed over bodies of water and other sensitive areas.
The state's first human case of eastern equine encephalitis since 2010 was reported last month, in a person over 50 from West Warwick. The disease also has been found in mosquitoes in Central Falls and Westerly.
